Background: There is a well-known relationship between induced labour and caesarean rates. However, it remains
unknown whether this relationship reflects the impact of more complex obstetric conditions or the variability in
obstetric practices. We sought to quantify the independent role of the hospital as a variable that can influence the
occurrence of caesarean section after induced labour.
As part of the Portuguese Generation XXI birth cohort, we evaluated 2041 consecutive women who
underwent singleton pregnancies with labour induction, at five public level III obstetric units (April 2005-August
2006). The indications for induction were classified according to the guidelines of the American and the Royal
Colleges of Obstetricians...

To evaluate how the country of origin affects the probability of being delivered by cesarean section when giving birth at public Portuguese hospitals. STUDY DESIGN: Women delivered of a singleton birth (n = 8228), recruited from five public level III maternities (April 2005-August 2006) during the procedure of assembling a birth cohort, were classified according to the country of origin and her migration status as Portuguese (n = 7908), non-Portuguese European (n = 84), African (n = 77) and Brazilian (n = 159). A Poisson model was used to evaluate the association between country of birth and cesarean section that...

PURPOSE: To evaluate the association between the Bishop Score and successful induction. STUDY STRATEGY AND SELECTION CRITERIA: We searched the PubMed and the lists of references of relevant studies to identify reports on the association between Bishop Score and achieving active phase of labour or vaginal delivery. DATA COLLECTION AND ANALYSIS: We abstracted crude or adjusted measures of association from studies. Summary odds ratio (OR) and summary hazard ratio (HR), and 95 % confidence interval (95 % CI) were obtained by random effects meta-analysis. Study heterogeneity was assessed using the I (2) test. RESULTS: Fifty-nine studies met the inclusion criteria....

A significant different allelic distribution, in Gilbert patients and in controls, was found for two promoter polymorphisms. Among patients, 82.2% were homozygous and 17.8% heterozygous for the c.− 41_ − 40dupTA allele; in control group, 9.9% were homozygous and 43.5% heterozygous for this promoter variant, while 46.6% (n = 75) presented the [A(TA)6TAA]. For the T>G transition at c.− 3279 promoter region, in patients, 86.7% were homozygous and 13.3% heterozygous; in control group, 33.5% were homozygous for the wild type allele, 44.1% were heterozygous and 22.4% homozygous for the mutated allele. The two polymorphisms were in Hardy–Weinberg equilibrium in both...

Objective: To estimate the prevalence of young people’s involvement in violence measured as participation in physical fights or being physically, sexually or emotionally abused. We also aimed to understand the role of social, demographic and other behavioural characteristics in violence. Methods: We evaluated 7511 adolescents (4243 girls and 3268 boys) aged 15 to 19 years old, enrolled in public schools. Information was obtained using an anonymous, self-administrated questionnaire. Results: The most frequently reported type of violence was emotional abuse(15.6%).Boys reported greater involvement in fights(3.6 vs.13.6%,p<0.001)and physical abuse (7.5 vs.19.5%,p<0.001).The prevalence of emotional abuse(16.2 vs.14.8%,p=0.082)and sexual abuse(2.0 vs.1.8%,p=0.435) was similar in...
